Good grief, I hope this isn't the start of another outbreak. I remember watching a program a few years ago about the Ebola epidemic...horrifying stuff.

I'd caught a mention of this in the news, but hadn't really followed it up. Had no idea it was hemorrhagic. That's all we need...easily communicable deadly plague...in todays world or passanger planes...SARS might have been a flash in the pan, but that doesn't diminish the possibility of something bad happening. (In fact, it's one of the most likely "doomsday" senarios IIRC.)

And it's happening in Johannesburg. :shock: Keep safe, Av.

(Yeah, these days virulent diseases worry me more than other kinds of doomsday scenarios. At least I can take some comfort in knowing that our national microbiology lab - located right here in Winnipeg - is right on top of this kind of research.)

Haha, I'm 500 miles from there right now. :D Seems they've identified it as a rodent-born arenavirus, associated with multimammate mice prevalent in east and west Africa. One additional case has been confirmed, and 91 people are being monitored. They think they've got it under control.

Ancient bones show tuberculosis older than thought

--------------------------------------------------------------------------------

By Michael KahnPosted 2008/10/14 at 7:03 pm EDT
LONDON, Oct. 14, 2008 (Reuters) — Scientists have discovered tuberculosis in 9,000 year-old human bones found submerged off Israel's coast -- evidence the disease is at least 3,000 years older than previously thought, researchers said on Wednesday.


The findings show how tuberculosis has evolved over thousands of years and provides a better understanding of ways it may change in the future, the researchers said.

"Examining ancient human remains for the markers of TB is very important because it helps to aid our understanding of prehistoric tuberculosis and how it evolved," said Mark Spigelman of University College, London, who worked on the study.

"This then helps us improve our understanding of modern TB and how we might develop more effective treatments."

Tuberculosis is an infectious bacterial disease typically attacking the lungs that newly affects about 9.2 million people each year and kills an estimated 1.7 million around the world.

The emergence and spread of drug-resistant germs makes treating it much harder and could make the disease even deadlier.

The international team, which also included researchers from Israel's Tel Aviv University, found the bones believed to be a mother and baby submerged off the coast of Haifa.

DNA analysis and bone lesions characteristic of tuberculosis showed that the skeletons from a 9,000 year-old Pre-Pottery Neolithic village were infected with the disease, the team said in the Public Library of Science journal PLoS One.

The village was located in a place that is now submerged.

Further tests showed that the strain was a type found only in humans and is similar to common bacteria that infects people with tuberculosis today.

Previously, the oldest confirmed human TB strain was from a group of Egyptians dating back to around 3,000 BC, said Helen Donoghue, a University College, London, researcher who worked on the study.

"We can tell that it was human because it was missing part of its DNA that is characteristic of the human lineage," she said in a telephone interview.

"The strain we have found as far as we can tell is identical to some of the bacteria that are going around and infecting people today," she added.

Good news I guess. Of course, TB has already mutated into a new strain that's causing a lot of death out here...they call it XDR-TB...extreme drug-resistant.

'Shaming' smokers makes it harder to quit: Study

Quote:
Years of anti-smoking laws and campaigns have amounted to a public shaming of smokers that could make it harder for them to quit, a group of UBC researchers argue in a new report.

There is an “urgent” need for governments to revisit their anti-smoking policies, the academics say, suggesting that the stigma around smoking could lead to patients hiding their tobacco use from doctors, and feeling desperate about ever kicking the habit. The policies run counter to how other addictions are treated by the public-health field, they argue.

“People are made to feel really, really bad about their smoking and are treated quite badly, but feel quite helpless in quitting,” said Kirsten Bell, a medical anthropologist at the university and lead author of a paper just published on the issue.

“They feel really negatively about themselves, but quitting seems like an impossibility … They’re not really given much support.”


Smokers are treated "quite badly"? I've not personally witnessed any smoker being verbally or physically abused, but if there is a stigma, and if non-smokers do feel resentment toward smokers, I think it might be due to the nature of smoking in public -- the smoke isn't just affecting the smoker, it affects the people around the smoker. But I don't have a problem with more and better gov't services to support smokers who are trying to quit.

Anyway, if you read the full article, it says the study is already being slammed by anti-smoking advocates as just "parroting" the tobacco industry's attempt "to portray anti-smoking efforts as an attack on individuals."

So, make up your own mind, heh.

New Alzheimer vaccine to be tested in Europe

VIENNA - A new vaccine against Alzheimer's, developed by the Austrian biotechnology firm Affiris, will soon be tested in six European countries, the company announced Friday.

Some 420 patients will be recruited to take part in clinical trials in Austria, Croatia, Czech Republic, France, Germany and Slovakia, Affiris said in a statement.

The AD02 vaccine, developed with British drugmaker GlaxoSmithKline, was already tested for safety and tolerability over the past year.

The clinical trials will now test its efficacy, with results expected as early as 2012, the company said.

ADO2 is meant to prevent the building up of beta-amyloid plaques in the brain, which cause the degradation of nerve cells and are believed to play a crucial role in causing Alzheimer's disease.

The vaccine works by causing the body to attack these plaques by producing more antibodies, Till Jelitto, a spokesman for Affiris, told AFP.

More specifically, these antibodies are meant to attack only the part of the beta-amyloid protein that causes the plaques, he added.

This would reduce the risk for patients, as the protein as a whole already exists in healthy individuals.

The current vaccine is therapeutic, meaning it is aimed at treating patients already affected by the disease. But if results are positive, the technology could also be used to manufacture a prophylactic, or preventative, vaccine, Jelitto said.

In 2001, tests for a first vaccine against Alzheimer's disease were conducted in the United States and Europe but had to be cut short after serious side effects emerged.

Another vaccine was tested in Sweden in 2005.

Alzheimer's disease, also known as AD, is a neuro-degenerative disease that affects cognitive functions, further impacting patients' behaviour and social adaptation.

The disease, which still has no known cure, affects about six million people in Europe every year.

Affiris is also working on vaccines against Parkinson's and atherosclerosis.

I have a particular hatred/fear/revulsion towards Alzheimer's, so I'm always hopeful about this kind of news.

Yes, absolutely. It is a form of death where your body keeps going for a time... :(

Yeah, it's a terrifying one. Hope good things come of this.

Bionic cat!! :shock: :D 8)

One hopes this will bode well for human medicine, too!

This merely confirms a belief long held by pretty much anyone who has worked in hospitals for any length of time - NEVER go into a hospital in the month of July if you can at all help it! :|
